Lenovo g550 model 20023 HDD SATA port type ?

I want to change my HDD, because it's broken and I need more info about the SATA port of my Lenovo laptop (G550 model 20023). I need to know if is SATA 1 type / SATA-150 or if is SATA II type / SATA-300.

Also please tell me if is possible to upgrade to a SSD disk? Thank you.
